Common Causes
- Dissolved (ferrous) iron in private well water
- Iron bacteria (IRB) producing slime and deposits
- Corroding galvanized iron pipes in older homes
- Iron and manganese combination (black/orange combined staining)
The Fix
An iron oxidizing filter (air injection system) at the point of entry treats iron before water reaches your fixtures, which addresses the source of the staining. ClearFlow measures your iron level and sizes a system accordingly; treatment capacity is defined by the manufacturer's published specifications.

Frequently asked questions
How do I remove orange stains from my shower?
For existing stains, white vinegar and baking soda or a commercial iron stain remover is the usual approach. To stop new staining, the iron needs to be treated in the water itself, typically with an oxidizing filter.
Why does my toilet have orange rings?
Orange toilet rings are caused by iron in the water oxidizing on the porcelain. Even very low iron levels (0.3 ppm) can cause visible staining over time.
Is iron in water a health concern?
The EPA regulates iron under its secondary (aesthetic) standards rather than health-based standards. Its main effects are staining of fixtures and laundry, metallic taste, and buildup in plumbing and appliances. Elevated iron can also indicate iron bacteria.
I'm on city water — why do I have orange stains?
Some municipal systems have older iron distribution lines that leach iron into water. ClearFlow can test your water to confirm the source.
